Non-formal education has been suggested as becoming more and more important in the last decades. As the aims of non-formal education are broad and diverse, a large variety of non-formal learning activities is available. One of the emerging fields in many countries, among them Finland and Germany, has been the establishment of non-formal laboratory learning environments. These laboratories were established in universities and research institutes to aim at enriching opportunities for primary and secondary school students to do more and more intense practical work, e.g. in chemistry. The primary rationale of these laboratories, in the beginning, was mainly to raise students’ interest in the fields of science and engineering, possibly inspiring them to pursue a career in these fields. However, recently the movement has started offering more programs aiming at all learners, but especially those students who are sometimes neglected in traditional science education in the formal sector. A focus on all learners is suggested to help raise students’ level of scientific literacy when connecting practical science learning with the societal and environmental perspectives of science. Chemistry learning connected to sustainability issues offers many contemporary topics that are often not yet part of the chemistry formal curriculum but can easily form contexts for non-formal learning. Because of its flexible character, non-formal education can help implementing aspects of sustainability into chemistry education and also can take a gander at the growing heterogeneity of today's students. This paper derives a joint perspective from two non-formal chemistry education initiatives from Finland and Germany focusing education for sustainability for both talented and educationally disadvantaged students in the foreground of a more general perspective on non-formal and sustainability education in chemistry.
Non-formal educational programs have several aims. For instance, they may aim to raise students’ motivation and interest towards science, to orient them towards science-related careers, to provide a broader and more authentic view on science and engineering, or to overcome shortages in school science teaching caused by limited budgets, time constraints, or lack in infrastructure (Stocklmayer et al., 2010; Coll et al., 2013; RSC, 2015). Recently, aspects supporting Education for Sustainable Development (ESD) have also been implemented into non-formal education (Garner et al., 2015), as also the examples discussed in this paper indicate. In this paper, we reflect on two quite different non-formal chemistry education initiatives from Finland and Germany in the foreground of a more general perspective on non-formal chemistry education, namely the focus on all learners including also those commonly not fully reached by traditional formal chemistry classes. The cases are provided by non-formal chemistry learning environments offered by universities, namely the Universities of Helsinki and Bremen. In the foreground of these concrete activities, the paper shall provide a perspective on and reflection of the different aims and possibilities of non-formal learning environments that are offered for primary and secondary chemistry education. The reflection includes also the perspectives of enriching chemistry learning with the goals and the contemporary contexts of education for sustainability (Burmeister et al., 2012).
There are several reasons why Finland and Germany were chosen as examples for this joint perspective paper. Non-formal learning, especially learning in non-formal educational laboratories located at universities, has become a very important feature in several countries. Germany and Finland were among them from the beginning. Finland implemented non-formal science education throughout the country in a coordinated approach. In Finland, non-formal education in science, mathematics, and technology-related topics is primarily provided by the LUMA Centre Finland, which operates non-formal learning all over the country in close collaboration with universities, companies, schools and many other stakeholders (Vihma and Aksela, 2014). Finland's national curriculum obliges schools to part-take in out-of-school education (Finnish National Board of Education, 2014), showing the support and formal appreciation for non-formal education on a national level. In Germany, a more decentralized approach to non-formal science learning is operated. Individual non-formal student laboratories in the sciences emerged all over the country to promote primary and secondary science education. Currently, more than 300 of those laboratories, in German Schülerlabor, exist (Hempelmann, 2014). Though less formal than in Finland, also in Germany this movement is officially acknowledged and supported by the Federal Ministry of Education and Research, especially when it comes to science learning for sustainability (LernortLabor, 2016). Both countries, but especially Germany, can also be seen as examples for growing heterogeneity and diversity among students, their achievement levels, their cultural backgrounds, and their interests. This is a challenge for more and more countries in the world in times of growing mobility and migration. Like schools, also non-formal education has to cope with corresponding challenges of growing heterogeneity and diversity. It is time to reflect to which extent non-formal education can help the whole educational system to support all students better with feasible science education respecting their different educational backgrounds and achievement levels (Affeldt et al., 2015).
Since the early 1970s, many typologies of formal, informal and non-formal education have been suggested (Coll et al., 2013). In 2012, the Organisation for Economic Co-operation and Development (OECD) defined formal education as an organized learning that has a specific structure, is located in formal institutions, e.g. school, and is connected to any kind of curriculum. According to their definition, informal learning refers to out-of-school learning which is unstructured and does not follow a specific curriculum (OECD, 2012). Furthermore, informal learning is voluntary and takes place mainly in the students’ leisure time. Examples include individual visits to a science exhibit, but it also concerns the consumption of science programmes on TV, reading of science articles found in public media, visiting a museum or a science center regardless of class and teacher (Stocklmayer et al., 2010), but also informal conversation about science-related issues with friends, parents, and peers (OECD, 2012). Typically, non-formal learning is considered to occur out of the traditional school environment, although this does not necessarily have to be the case (Garner et al., 2014). It tends to have a specific structure and is often connected to various types of programmes or curricula (Coll et al., 2013). The UNESCO (2012, p. 10) defines non-formal learning as follows:
“Non-formal learning is learning that has been acquired in addition or alternatively to formal learning. In some cases, it is also structured according to educational and training arrangements, but more flexible. It usually takes place in community-based settings, the workplace, and through the activities of civil society organisations.”
According to Eshach (2007) the main difference between non-formal education, even if connected to official school activities and formal education, is that non-formal education takes place in less formal settings. Furthermore, learning in non-formal education is typically not assessed, and the learning goals are not restricted by any official curriculum.
The distinction between formal, non-formal and informal education is not always easily recognizable, nor straight forward (Garner et al., 2014). For instance, Coll et al. (2013) point out that both terms, informal and non-formal, although officially defined and widely used, are often incoherently applied. Quite frequently both terms are indiscriminately used to describe any kind of learning event which takes place outside of school and/or outside the regular curriculum. Furthermore, it is also debatable, whether learning experiences outside the school campus should always be labeled as informal or non-formal education, because they can also form part of the official school curriculum, embedded in the formal learning process, and a compulsory learning experience for all students. The complexity of distinguishing between formal and non-formal education is also evident when considering non-obligatory courses provided within the schools. Generally, these offerings belong to the formal sector, but due to the fact that they are non-compulsory and not always structured by a specific curriculum, they contain characteristics typically associated with non-formal education (Garner et al., 2014). Regardless of these complexities, in this article we use the term non-formal education to refer to organized science education that happens in out-of-school settings, whether or not it is tied to any structured curriculum.
Non-formal educational programs are suggested to play an important and growing role in supporting students’ learning. Non-formal learning environments can better provide flexible and individually adaptable programs than school science classes (Rennie, 2007). Working materials can be made adjustable to the current student's interest, performance and knowledge level (Gallacher and Feutrie, 2003). The loose connection to the formal curriculum also gives non-formal education the opportunity to implement issues that are either more specific, or are more relevant for the students in one way or another. Non-formal education gives more freedom of what to teach relating the heterogeneity of learning groups (Hofstein and Rosenfeld, 1996) and includes the ability to integrate multidisciplinary topics and cutting-edge topics, such as sustainability issues, which are currently not implemented in many curricula and syllabi (Garner et al., 2015). Interdisciplinary learning including chemistry, physics and biology contexts may be more easily implemented into non-formal settings.
Student-centered, inquiry-based learning, where young people operate as “researchers”, can help students to understand how scientific knowledge is constructed (NRC, 1996). Such approaches are more easily organized in non-formal education because of better resources, higher flexibility, and additional time (Mantzicopoulos et al., 2008). Therefore, non-formal education is a good door opener for innovative pedagogies, materials, and inquiry learning (Garner et al., 2015). Student-centred approaches implemented by innovative, creative learning environments can be directly oriented towards students’ lives and help them construct knowledge (Affeldt et al., 2015). Linking formal education with informal or non-formal settings can have an influence on the curriculum and pedagogy in the formal educational system by allowing teachers to learn about corresponding teaching approaches in the non-formal educational environment (Garner et al., 2014). Tolppanen and Aksela (2013) suggested that non-formal education also can give students orientation and self-confidence regarding their future careers. Thus, non-formal education provides the opportunity to connect gaining knowledge with interest, learning about authentic societal issues from science-related research, and orientation about professions. All these are essential components of relevant chemistry education as suggested by Stuckey et al. (2013). Characterised by a high degree of flexibility, openness to change and innovation in its organisation, pedagogy and delivery modes, non-formal education caters to diverse and context-specific learning needs of students. Thus, there is another benefit of non-formal education. In the context of science for all, activities from informal and especially from non-formal education offer specific chances to learn more or different science than in regular classes in school.
Another contribution of non-formal learning is the role it can play in teacher training (Garner et al., 2014, 2015; Vihma and Aksela, 2014). Non-formal learning activities can be useful in the case of developing teachers’ content knowledge and pedagogical content knowledge (PCK). Furthermore, non-formal education offers opportunities for teachers to learn about new developments in science and technology while learning about corresponding teaching approaches, experiments, and pedagogical innovations. In addition, non-formal education provides pre- and in-service teachers a platform to be introduced to topics that are not yet implemented into the curriculum. Finally, teachers can also learn to cope with some of the educational challenges they may face in the near future, for instance, regarding growing heterogeneity and education for sustainable development (Affeldt et al., 2015).
Also, Eshach (2007) and Griffin (2004) suggested an intense connection between learning contexts to effectively link non-formal and formal science education so that teachers are crucial for the success of the non-formal learning experiences. If the programme in the non-formal learning environment is not attuned to the learning in school, the students frequently do not connect experiences and knowledge gained in the non-formal setting with their formal learning in school. In their summary of the literature, DeWitt and Storksdieck (2008) conclude that teachers should integrate out-of-school trips into their class curriculum, preview and follow-up sessions during class time, and provide opportunities for students to engage in inquiry-based exploration and hands-on learning while on excursions. A project described by Garner et al. (2015) operated a corresponding structure. Findings from this project indicate that visiting non-formal learning environments, e.g. student laboratories in the university, have the potential to affect students’ attitudes and motivation towards chemistry learning when thoroughly linked to the school curriculum.
Some researchers point out that motivation, enthusiasm, and eagerness can be long-term effects of visiting non-formal learning environments (Rennie, 1994; Rhodes, 2013). Other researchers criticise that benefits of non-formal learning environments are sometimes only of short-term effect, e.g. supporting science-related self-concept, knowledge gains, and increasing interest in science (Falk and Dierking, 1997; Wendt et al., 2007; Brandt et al., 2008). Reasons for the limitations in the positive effects of visiting a non-formal setting are suggested in the insufficient follow-up work and a lack of catching up the previously learned contents in school (Brandt et al., 2008). In this context, Wolins et al. (1992) have argued that multiple visits and the linkage to the syllabus may help positive effects persist over time. It was also suggested that social interactions in non-formal education can be important, as students can reflect in a more open atmosphere what they have learned with like-minded students, with their teachers and staff from the non-formal learning provider (Rahm, 2004).
With a view to an often discussed achievement gap between students, Rennie (2007) pointed out that non-formal learning environments should be flexible and adaptable to different learning groups so that the programme can consider individual learning conditions. Student groups with a high degree of heterogeneity and diversity make individual advancement in school education often difficult. In a non-formal setting, the staff–student-ratio is often much better for individual support as there are more tutors per class during the visit than in school. Garner et al. (2014) also described that teachers started following individual students’ behaviour with great interest. Teachers started seeing their students from a different angle and were often surprised by the working behaviour of the lower achieving students.
Beyond the quality of the learning experience and its interconnectedness with formal education, the greatest limitation in non-formal learning might be that not all non-formal learning opportunities are available for all students. Non-formal learning environments generally are better available in urban areas, especially those with academic institutions and industry. Educational policy has also to avoid that the visit of non-formal learning environments is to become an issue of availability of financial support. This is to avoid that socio-economically advantaged groups get further advantage by visiting the non-formal environment compared to those groups who are hindered just by a missing budget. Another limitation is that not every subject will be available in every city. Schools from rural areas generally have fewer possibilities to visit authentic research and industry environments, especially related to a specific subject. In such cases, it is at least much more demanding to organize corresponding learning experiences. A potential solution might be to invest in mobile labs that can offer the non-formal experiences in schools or in cooperation with local and regional providers of any other kind of non-formal learning experiences, e.g. Youth Centers.
Dealing with authentic and current issues, which are related to the life of children or young adolescents, can have a relevant and motivating character. However, many curricula for formal chemistry education are still quite traditional, neglecting certain aspects of relevant science education, especially the societal dimension of learning, education for sustainability, and many cross-curricular goals (Hofstein et al., 2011; Burmeister et al., 2012; Belova et al., 2016). The curricula and assessment requirements, as well as a lack of time, often results in new topics, such as nanotechnology, climate change and sustainable issues in general, to be implemented into the formal curricula slowly (e.g., Burmeister, Schmidt-Jacob and Eilks, 2013). Furthermore, generally, the adoption of innovations in school often lack both sufficient support mechanisms and recognition of the importance of teachers’ underlying beliefs, attitudes and knowledge (Van Driel et al., 2005).
With reforms to improve school curricula taking place across the world, non-formal education has proven to be effective for innovative approaches (Hoppers, 2006). Learning in non-formal settings is not restricted to official syllabi and guidelines (Eshach, 2007). A non-formal learning environment gives the freedom to deal with issues either more specifically, or more holistically, depending on what the students and on what the teachers want. Additionally, it allows the fast and direct implementation of current socio-scientific issues, e.g. from the sustainability debate (Garner et al., 2014). It provides the opportunity to deal with relevant, cutting-edge topics that are not yet present in the national curricula or textbooks. New topics, like sustainable chemistry or molecular gastronomy, can be implemented faster into chemistry education because of the flexibility of non-formal learning environments and the corresponding expertise of their staff in universities, research centres, or industry. Furthermore, non-formal learning environments can also give students more freedom and time to dig into these issues and to discuss them from both a scientific and a societal perspective.
In non-formal settings, students can have a deeper learning experience, as they deal with topics that are more closely connected to their daily life than many issues from the formal chemistry curriculum. For example, sustainable mobility offers possibilities for inquiry-based experiments, like synthesis of biofuels, inquiry of a hydrogen car model and production of fiber composites or metal foams (Garner et al., 2014; Affeldt et al., 2015). Accordingly, non-formal education can be a way to make science education more relevant and provide the students a better perception of the relevance of science and its related technologies.
Non-formal learning can both offer possibilities for additional experimental learning opportunities and help to develop new pedagogies and materials for practical work for later implementation in school classrooms too (Garner et al., 2015). Non-formal learning, with its greater freedom, also provides the opportunity to try out new activities for a more student-centred pedagogy. They can be more student-centered, inquiry-based, interactive, and should provoke cooperative learning (Eshach, 2007). Non-formal learning environments provide a platform for innovations in the curriculum and its related pedagogy (Garner et al., 2014). The open atmosphere of a non-formal learning environment offers the chance for applying new forms of learning. In this context, the non-formal setting can be a platform for testing inquiry-type experiments before transferring them into school conditions. Out-of-school laboratories have the opportunities to try out different pedagogical approaches for educational content. A better student-to-teacher-ratio gives the possibility to implement more challenging experimental tasks and procedures. Also, non-formal learning environments are often connected to universities and chemistry departments. Thus, the better equipment and the supervision by experienced academic staff allows more flexibility in testing out innovative activities, like new experiments and experimental techniques which are not yet used in formal learning.
Non-formal education gives the chance to try out several variations of different experiments, also with respect to micro-scale and low-cost techniques. Thus, non-formal education can be a door opener to try out new forms of teaching and learning activities and to spread them. The same holds true for approaching chemistry with different contexts, media types, or tasks to see what works best and is most motivating. Instructions for experiments in formal school education are usually more sober-designed. Teachers often do not have the time to develop completely new, creative teaching and learning materials, e.g., instructions for experiments. Non-formal learning environments offer opportunities to try out new forms and designs in teaching and learning materials, e.g., innovative instructions for bringing science closer to daily life. Creative approaches, e.g., experimental instructions in the form of comic books, on-line forums, blogs, and on-line news reports developed in a non-formal laboratory can support students’ motivation and help also lowering barriers towards experimental tasks, which are often caused by linguistic deficits among the students (Affeldt et al., 2015).
In Germany, a more decentralized movement spread out over the whole country within the last 10–15 years (Di Fuccia et al., 2012). Until today, more than 300 non-formal learning centres for primary and secondary education have been established to support science and technology learning beyond the classroom (Hempelmann, 2014). Most of the laboratories are hosted and connected to universities, larger research centres, or industrial plants. Most of them are today networked by Lernort Labor, a joint educational platform for any out-of-school non-formal learning environments for primary and secondary school students (Hempelmann, 2014). In Germany, the name Schülerlabor was created for this kind of non-formal student laboratories aiming to promote primary and secondary science education. The name Schülerlabor can be translated as student laboratory. The word ‘Schüler’ in German refers to school pupils exclusively, not to university students (Garner et al., 2014). The Schülerlabors were founded in the last two decades, most of them by universities. At first, their primary role was to overcome a shortage in young people embarking into academic careers in science and engineering. Over time, however, the idea of the Schülerlabor adapted into a broader movement, with the aim to support science learning on all levels by offering all students out-of-school experiences and practical lab work, possibly now implemented in traditional schools due to a lack of equipment, time, finances, or overall quality in the school lab facilities (Di Fuccia et al., 2012). Quite often student teachers also take part in the Schülerlabors as part of their teacher training. Schülerlabors are also a place for teachers’ continuous professional development (Garner et al., 2014).
The camp provided students with the opportunity to work on projects related to cutting edge topics, typically not addressed in schools. Examples of these projects include designing a sustainable city, creating an algorithm to make garbage collection more efficient, or examining how the use of ICT can improve literacy in developing countries (Tolppanen and Aksela, 2013; Tolppanen and Tirri, 2014). Many of the projects were related to chemistry. For instance, in 2014, the Climate change group examined emissions produced by biodiesel, the Energy group examined the efficiency of PEM fuel cells, and the Material science group compared the use of gallium arsenide and silicon in solar cells (MyScience, 2014).
One of the reasons for the popularity of the Millennium Youth Camp was that it was created to meet a specific need of a certain group of students, in a way that formal education may not be able to. In the case of the Millennium Youth Camp, the focus group was gifted students, interested in sustainable development and international relations. However, the aim was not only to provide participants with the opportunity to work on a relevant topic, but also to interact with likeminded students, as well as inspire them by providing the opportunity to meet top experts of the fields they were interested in. These encounters included meeting Shinya Yamanaka, the winner of the Nobel Prize in biology, and Linus Torvalds, the creator of the Linux operating system, found in all Android devices. As the research conducted on the camp shows, attendees felt that the camp met their academic and social needs very well (Tolppanen and Aksela, 2013).
Non-formal educational programs, such as the Millennium youth camp, are also able to deal with timely issues, helping overcome the challenges related to the slow reformation process of national curricula. In addition, they are not constrained by a single topic, but rather, are able to provide a wide range of different topics, helping meet the individual needs of students. At the Millennium Youth Camp, students were able to choose their theme of interest out of ten options, and in most cases, had a strong influence on the research question of the project. All of these themes were multidisciplinary in nature, and would not fit into any particular school subject as such. Furthermore, students were given autonomy over their projects, giving them the opportunity to direct their learning towards their key interests (Tolppanen and Aksela, 2013; Tolppanen and Tirri, 2014). Experts working with the participants felt that the projects helped increase knowledge, but in addition, the projects supported the development of creative thinking and broadening the participants view on academic and professional opportunities (Tolppanen and Tirri, 2014). Experts also mentioned that the projects enabled participants the opportunity to work on timely projects, giving them an idea on what type of issues scientists work on today.
The research conducted at the Millennium Youth camp and other similar programs plays an important part in developing formal education and pedagogical practice. As an example, Finland's new national curricula put emphasis on developing students’ ability to live in a sustainable way (FNBE, 2014). This reform gives teachers the freedom to, at least to some extent, freely choose the sustainability topics that they find timely and interesting to students. The studies conducted on the Millennium Youth Camp gives teachers an idea of what sustainability themes students are interested in (Tirri et al., 2012) and how these issues could be addressed in practice (Tolppanen and Aksela, in press).
The target groups of the project are very heterogeneous secondary comprehensive school science and chemistry classes in grades 5–10 (age range 10–16). A total of six modules has been developed to date. Topics encompass, among others, water quality, alternative plastics, sustainable mobility, and alternative ways of energy storage. Each of the modules offers a set of roughly 20 experiments of which students and teachers can select the ones that suite them best. The project involves a newly developed model of differentiation which intends to include all learners (Affeldt et al., 2015). The differentiation model takes into account students’ diversity in their interests, cognitive achievements, problem-solving skills, and linguistic capabilities (Fig. 1). The aim of differentiated instructions is to enable all students to solve each of the tasks on their own. All of the experimental tasks are developed with regard to a student-centered, inquiry-based pedagogy. The experimental instructions are structured to allow students to select a mode, ranging from open to structured inquiry by providing graduated learning aids. The model includes that different tools (help cards) are available to support students at different performance levels. The learning aids are given at the phenomenological-descriptive, the verbal-explanatory, and the sub-microscopic or formal-representational levels. Aside from this, learning aids focusing on content and on the process of inquiry are included. Additionally, aids are provided when dealing with linguistic heterogeneity among the students. Each set of laboratory instructions also contains a set of language-sensitive tools, e.g. cloze texts or word lists.
To better connect science learning with real life, as well as to lower the linguistic barrier towards practical work, the developed experimental instructions aimed to acknowledge the way today's students’ community. Therefore, comics, blogs and diverse forms of social media, e.g., Facebook, Instagram, and Twitter, were used as elements for the creation of innovative and student-oriented teaching and learning material. The aim was that students would connect situations from their daily life with scientific issues, helping them develop right ideas of natural phenomena. Findings from the accompanying research indicate that students enjoy learning with the created teaching and learning material project (Affeldt et al., 2015).
In the non-formal chemistry learning environment, students are confronted with current and authentic issues related to the fields of science and technology. These issues also provide a platform to discuss the related societal challenges. Furthermore, this project can contribute to curriculum innovation and continuous professional development of teachers, as innovative and sustainable experimental techniques are developed and are conveyed to teachers in the frame of pre- and in-service education. Networking of schools with the student laboratory is realized in working with selected partner schools and educational institutions outside formal education, like tutoring clubs or local parent initiatives.
Another trend is that in increasingly inter-connected and technologically advanced societies internationally agreed goals, such as the Millennium Development Goals (MDG), Education for Sustainable Development (ESD), or Education for all (EFA), have set the agenda for global development. This trend suggests that non-formal and informal education are of growing importance (UNESCO, 2012). This is also seen in the three educational strategic objectives set by UNESCO for 2014–2021 (UNESCO, 2014). The first of these objectives describes the support of member states in developing education systems to foster high-quality and inclusive life-long learning for all. This includes lifelong learning policies and vocational education. The second objective explains the empowerment of learners to be creative and responsible citizens. This includes the orientation in a socio-cultural environment and the participation in a democratic society. The third objective aims at the Education for All. Non-formal science education having a focus on sustainability education, as it can be seen from the previous sections, provides a great opportunity to contribute to all of the three objectives.
Responsible citizenry for all is a goal also set by the European Union (EU). In the framework of Science Education for Responsible Citizenship, the EU defines key objectives, which shall generate a sustainable effect on the society (European Commission, 2015). A similar concept is integrated into the ideas of Education for Sustainable Development (ESD) (Burmeister et al., 2012). Furthermore, the Science Education for Responsible Citizenship includes the collaboration between non-formal/informal and formal education (European Commission, 2015).
The two examples given above suggest that non-formal education provides unique opportunities to promote science learning and sustainability-related skill development for all students, in chemistry education and beyond. The Millenium Youth Camp was developed to meet specific needs of a certain group of students: talented students, interested in science, technology, sustainable development and international relations. Here the non-formal environment shows its unique opportunity to support the needs of these students, promote learning with like-minded students, and to motivate them to pursue their engagement and future profession in fields of science, technology, and sustainability. A totally different group of learners is the focus in the German project, where non-formal learning activities were created keeping in mind the heterogeneity and diversity of today's students, especially those with disadvantaged educational biographies. The project helps lowering the gap between high and low achievers and motivate all students to engage with science and sustainability with a more holistic approach. It is suggested that even among the students with less advantaged educational biographies, e.g. caused by a migration or even refugee background, we can find talents and interested students for careers in science and technology – in the academia or via any other vocational training. Independent from the career issue, educational policy suggests that every citizen needs skills for responsibly acting in society and contributing to its sustainable development. This is a goal non-formal education also can contribute to, especially by focusing on less skillful students, who tend to have less developed attitudes towards science and sustainability. However, the innovation does not stop in the non-formal environment, as the new content can be made accessible to teachers and learners, and new pedagogical approaches can be tested and developed, so that they can be later implemented into formal education more easily. This has already been seen in the German example, as the created model is now ready to be tested in the formal school setting.
In 2012, Burmeister et al. described four different approaches for the integration of ESD with chemistry education. These range from a different laboratory practice with less hazardous chemicals, via accessing new content, context- and socio-scientific issues-based learning, towards changing school life to innovative practices for sustainability. It is suggested that the non-formal educational sector can contribute to all the four roles. Table 1 suggests selected contributions of the non-formal learning environment that might offer support to the different models suggested by Burmeister et al. (2012).
Model | Contribution from the non-formal educational sector | |
---|---|---|
1 | Adopting green chemistry principles to the practice of science education laboratory work | Developing innovative and sustainable experimental techniques in the non-formal laboratory, trying them out in a well-equipped environment, and conveying them to teachers when visiting the non-formal learning environment |
2 | Adding sustainability strategies as content in chemistry education | Contending students and teachers with current and authentic research in sustainability related fields of proximity to the scientific community |
3 | Using controversial sustainability issues for socio-scientific issues which drive chemistry education | Confronting students with authentic issues of sustainability currently discussed in science and technology in direct contact with researchers from the corresponding field |
4 | Chemistry education as a part of ESD-driven school development | Creating innovative structures by systematic networking of schools with the non-formal learning environment as part of school development |
However, non-formal learning in chemistry and for ESD is also, to some extent, limited in range and influence. Non-formal learning and teaching activities are generally only available in urban areas with universities, research institutes, and industry and offer out-of-school learning mainly for learning groups from the regional environments. Thus, not all students have the opportunity to learn in a more varied and contextualised way in the non-formal learning laboratory because of the significant distance to universities in some of the rural areas. The Millenium Youth Camp is not restricted by geographical constraints, but is only able to cope with a very limited number of students. Therefore, many students do not get access to this unique opportunity to learn about science and sustainability, offered by the non-formal learning environments as described in this paper. Furthermore, it is typically up to the teacher whether a trip to the non-formal environment is or can be organized or whether support is given for a successful application to the Millenium Youth Camp. In the case of Germany, there are currently some 8 million students visiting schools at the primary to upper secondary level, however only about 700000 of them visit non-formal student science laboratories in universities, research centres, or industry per year (LernortLabor, 2016). In the case of the Millenium Youth Camp only 30–60 students from 1000 applications were able to be selected. This observation might remain as long as visits of non-formal learning sites are not made available area-wide and compulsory for all classes on the educational policy level. The approach in Finland by the LUMA Centre Finland is nationwide, however also here it depends on the teachers and schools to which extend the schools can accept the offer to use the non-formal learning environments in chemistry and to which extend. There are also limitations in innovations in the curriculum and pedagogy as well as teacher continuous professional development by working with and in the non-formal learning environment. Only those teachers being able to visit the non-formal learning environment will have direct access to the environment and can learn while experiencing the non-formal setting with the students. So far there is some research, although still rather limited, on the effect of non-formal learning environments on students’ cognition. Concerning the effects on curriculum innovation and teachers’ learning in the non-formal learning in chemistry, there is hardly anything known based on research evidence – as is the case with the area-wide distribution of non-formal learning experiences in comparison to urban and rural areas.
Curriculum development and development in the pedagogy of science teaching is done in both initiatives by scientists and curriculum experts from chemistry education research. The different learning activities can be linked with the national curricula and syllabi, but also can go beyond, as it is the case in the Millennium Youth Camp. The non-formal education sector, it is suggested, can promote a faster implementation of up-to-date, relevant issues and findings in science and technology than traditional school innovation and syllabus change can do. There are many opportunities in the non-formal settings to develop innovative teaching and learning pedagogies and materials with potential for the adaptation in typical everyday science classes in school, although the process of transfer from non-formal to formal education is an area that needs more research and development. In both of the described cases, the teaching and learning materials were designed based on a research-funded development strategy. However, it is not clear to which extent this is the case for many other non-formal educational initiatives since many of them are mainly reported on an anecdotal basis.
Both projects presented in this paper show a high potential of non-formal learning activities to contribute to the reform of curricula and pedagogy in science education, but it is not completely clear how the formal educational sector might best benefit from the non-formal educational initiatives. However, implementing the lessons learned into formal education is important, as not all schools have the opportunity to benefit from non-formal educational programs, as has been discussed. Another approach to overcome the pitfall that not all students can visit the non-formal laboratories in the universities would be to invest in mobile or virtual labs to allow all students, also in rural areas, the non formal learning experience. However, in this case research has to reveal whether mobile or virtual non-formal laboratories offer similar potential to the student in terms of motivation and the perception of authenticity.
Concerning ESD, non-formal education is a very prominent sector to help innovate formal science and technology education. Here one needs to ask, will there be similar potential in adopting other important areas of future education, such as, modern materials, current healthcare, or nano-science education, and how this needs to be conceptualized. It also needs to be asked how different providers of non-formal laboratories can better benefit from each other, e.g. in the field of ESD. Exchange between the laboratories nationally and internationally as well as adopting programs from one laboratory to another does not seem to be very common yet. Joint activities and reflections as they cumulated in this article, as well as exchange of staff and materials, would support learning from each other. This would also help identifying good practices to be disseminated on a wider scale. For the universities of Helsinki and Bremen this process has already started and it is intended to continue and extend this cooperation with further partners.
In summary, the field of non-formal – as well informal – science and chemistry education is growing. Research based understanding of the corresponding effects and the mechanism is also emerging, though still limited (Osborne and Dillon, 2007; Garner et al., 2014). There is not much research on the long-term effects, nor understanding on how non-formal chemistry learning affects learners with different educational backgrounds. The examples here show that there are positive perceptions and positive short-term effects, both among very talented students, as well as those with disadvantaged educational biographies. However, the focus of research and evaluation also needs to be broadened. Aside from motivation and attitudes, more research is needed on cognitive achievement, skills development, vocational orientation or career success – or the questions of the influence and potential effects of the non-formal educational sector on the curriculum and the teachers. Also, as suggested by Holliday and Lederman (2014), the practices and professional development of staff working in non-formal learning environments is an issue that needs more intense research and research-based development (Holliday and Lederman, 2014). Though there is a lot of potential, non-formal learning should not be over emphasized, as it is difficult to give all learners and teachers the chance for corresponding learning opportunities. This raises the question of whether new types of non-formal learning environments, e.g. remote laboratories, that can be visited virtually, are needed. Though non-formal education has increased much in the past years, it seems that the quest for finding best practices and understanding their effects has only started.
